[0018] Please see Figure 1-6 A pressing and processing device for polycarbonate polyester sheets includes a processing box 1. Both sides of the front end of the processing box 1 are connected to doors 3 via hinges 4. A base 2 is connected to the bottom of the processing box 1. An isolation frame 5 is connected to the bottom of the inner side of the processing box 1. A lifting cylinder 6 is installed inside the isolation frame 5. A support frame 7 is sleeved on the upper end of the lifting cylinder 6. Both ends of the support frame 7 are connected to the bottom inner side of the processing box 1. An ejector block 8 is embedded in the middle of the top of the isolation frame 5. The piston rod of the lifting cylinder 6 is connected to the bottom of the ejector block 8. By utilizing the cooperation between the isolation frame 5, lifting cylinder 6, support frame 7, and ejector block 8, rapid demolding of the pressed sheet can be achieved, thereby improving demolding efficiency. A limiting block 11 is provided at the top center of the frame 5. An upper mold 10 is provided inside the limiting block 11, and a lower mold 9 is provided directly below the upper mold 10. A hydraulic cylinder 12 is installed at the top of the processing box 1. A hot pressing block 13 is connected to the bottom of the hydraulic cylinder 12. The top of the hot pressing block 13 is provided with a grid-shaped reinforcing rib 14. The grid-shaped reinforcing rib 14 significantly reduces the weight of the hot pressing block 13, reduces the inertia of the moving parts, and reduces the heat capacity, resulting in faster heating and cooling, energy saving and improved efficiency. A resistance wire 15 is provided inside the hot pressing block 13. Connecting blocks 16 are connected to both ends of the hot pressing block 13. Two guide rods 17 are passed through each of the two connecting blocks 16. Through holes 18 are opened at the four corners of the upper mold 10, and the four guide rods 17 pass through the four through holes 18 on the upper mold 10 respectively.

[0019] Among them, the support frame 7 has an inverted U-shaped structure.

[0020] The top-out block 8 is in contact with the isolation frame 5 on all four sides, but not connected to it.

[0021] The number of hinges 4 is set to four, and the four hinges 4 are arranged in pairs opposite each other about the box door 3.

[0022] The bottom of the guide rod 17 is flush with the bottom of the upper mold 10.

[0023] The upper surface of the ejector block 8 is flush with the bottom of the lower mold 9.

[0024] Among them, the four guide rods 17 are arranged in pairs opposite to the two connecting blocks 16.

[0025] The upper mold 10 and the lower mold 9 are in contact but not connected.

[0026] The working principle and usage process of this utility model are as follows: First, the operator opens the box door 3 connected by the hinge 4 and places the pre-prepared layered polycarbonate polyester material into the cavity of the upper mold 10 and the lower mold 9. At this time, the hydraulic cylinder 12 is in a retracted or standby state, driving the hot pressing block 13 to the top. The lifting cylinder 6 is also in a retracted state, and its piston rod retracts, so that the upper surface of the ejector block 8 is flush with the bottom of the lower mold 9, without interfering with the lower mold 9. Then, the hydraulic cylinder 12 is started, so that its piston rod extends downward, pushing the entire hot pressing assembly downward. During the downward movement, the hot pressing block 13 moves downward along the four guide rods 17 through the connecting blocks 16 on both sides, ensuring that the hot pressing block 13 can only move vertically and will not deviate or twist, thus ensuring the pressing quality. The hot pressing block 13 first contacts and applies huge pressure to the middle plate material. Meanwhile, the resistance wire 15 embedded inside the hot press block 13 is energized and heats up, transferring heat to the stacked materials coated with adhesive in the middle. Under the combined action of high temperature and high pressure, the polycarbonate polyester sheet softens, while the pressure forces the multiple layers of materials to be firmly pressed together by the intermediate adhesive, expelling air bubbles between the layers and ensuring complete contact and adhesion. After the preset heating time and pressure are reached, the resistance wire 15 stops heating and enters the pressure holding and cooling stage, maintaining pressure until the sheet is fully cured. After curing, the piston rod of the hydraulic cylinder 12 retracts upward, driving the hot press block 13 to rise. Then, the lifting cylinder 6 is activated, and its piston rod pushes upward, pushing the ejector block 8 to move upward. Since the upper surface of the ejector block 8 is flush with the bottom of the lower mold 9, the upward-moving ejector block 8 smoothly lifts the sheet metal workpiece that has been pressed into shape inside the upper mold 10 and the lower mold 9. The operator can easily remove the finished sheet metal from the upper mold 10 and the lower mold 9. After the part is removed, the piston rod of the lifting cylinder 6 retracts, driving the ejector block 8 to descend and return to the initial position flush with the top of the isolation frame 5, preparing for the next processing cycle. Because the ejection force is uniform and fast, the problems of workpiece damage or low efficiency that may be caused by traditional demolding methods are avoided. During this process, the grid-shaped reinforcing ribs 14 on the top of the hot press block 13 not only ensure that the hot press block 13 has sufficient structural strength and rigidity under high pressure to prevent deformation, but also significantly reduce the overall mass and heat capacity of the hot press block, so that it can reach the set temperature more quickly when heating and cool down more quickly when cooling, greatly shortening the production cycle and saving energy.
